Who held the Buy Box, when, and what it cost you.

See who really holds
the Buy Box

Behind every buy button, prices move, sellers rotate and Amazon steps in. WhoHeld keeps the record of it, on every market you sell in.

Illustrative figures, not client results. Your own numbers come from your own tracked catalog.

The invisible war behind the buy button

As a vendor or 1P brand, you do not hold the seller account. So Amazon shows you almost nothing about who takes the Buy Box on your own products, when, and at what price.

Holders rotate while you look away

Between two weekly reports, the Buy Box on your products can change hands many times. You see an average. You never see the rotation.

Cost: revenue booked by someone else, invisible in your reports.

The Buy Box simply disappears

Amazon can suppress the Buy Box on your listings. No banner, no email. Your conversion drops and nobody tells you why.

Cost: pages that stop selling while traffic stays.

Sellers settle on your listings

Third-party sellers come and go on your detail pages. Some stay. Their footprint grows one product at a time.

Cost: price erosion and a weaker annual negotiation.

One product, four jobs

Every chapter of the app, organized around what a vendor team actually has to do each week.

How it works

Three steps, and the first one takes minutes.

01

Plug your catalog

You give us ASINs and market segments. No seller account, no API keys on your side, nothing to install.

02

We watch every market

Your catalog refreshed by activity: every 24 hours for the products on your Hyper Care list and for 30 days after a Buy Box loss, at least every 28 days otherwise. In Lead+, a hero pack of 50 products checked every hour. Honest cadences, written into the contract. The market segments in your scope are swept monthly, without a contractual commitment.

03

You act

Alerts when something moves, a Monthly Business Review refreshed every Monday (Lead), and an evidence pack for the annual negotiation (Lead+).

Simple pricing, per market

Per marketplace, per month, excluding VAT. Unlimited users. Available on 11 Amazon marketplaces*.

One quarter of unnoticed Buy Box loss can cost more than a year of WhoHeld.
